There does not seem to be a (genuine, unbiased) consensus about
whether 10GbaseT or SFP+ is going to "win out" for host

direction of SFP+ on the basis that server manufacturers seem to be
shipping SFP+ 10G kit, and the cheap 1U ToR switches are largely SFP+
Intel is starting to ship with 1/10GBASET LOM IMO this will push the
market to BASET, that and the cost is radically less. If you add up the
SFP+ optics and cabling costs these are easily more than many ToR
Yes. That is a popular, but in my experience not majority, opinion.
As I said: at this point, I don't think there is consensus. Obviously
you will disagree ;o)
switches. Also there are dense 10GBASET switches that can run at line
rate and drive distance to ~100M, since this is a Cisco focused mailer I
will leave company names off...
Why? Feel free to name names.
Extreme x650 is 24-ports. We've got some. They're reasonable devices,
and cheap.
My understanding was "never", based on vendor discussions.
Specifically, I believe the SFP+ is unable to provide sufficient
power to drive a 10GbaseT, full stop.
While the BER is a bit higher on BASET the above can be done today
Do you mean it's possible to purchase a 10GbaseT SFP+ today? From whom?
